You will need to use the Hardy Weinburg equation.
\[1 = p^2 + 2pq + q^2\]
where p^2 is the frequency of the dominant homozygous individuals, 2pq is the frequency of heterozygotes and q^2 is the frequency of recessive homozygous individuals in the total population.
Is that helpful enough, or would you like to work through the problem in more detail?
